Subject: [PATCH 6/8] mmc: dw_mmc: constify dw_mci_idmac_ops in exynos back-end
Date: Tue,  6 Nov 2012 22:55:31 +0100	[thread overview]
Message-ID: <1352238933-4886-7-git-send-email-arnd@arndb.de> (raw)
In-Reply-To: <1352238933-4886-1-git-send-email-arnd@arndb.de>

The of_device_id match data is now marked as const and
must not be modified. This changes the dw_mmc to mark
all pointers passing the dw_mci_drv_data or dw_mci_dma_ops
structures as const, and also marks the static definitions
as const.

drivers/mmc/host/dw_mmc-exynos.c: In function 'dw_mci_exynos_probe':
drivers/mmc/host/dw_mmc-exynos.c:234:11: warning: assignment discards 'const' qualifier from pointer target type [enabled by default]
